Design and run a vibration analysis on a 1m cantilever beam with a cross-section area of 5 cm x 10 cm. You may use NASTRAN (Nx NASTRAN, FEMAP, ANSYS or PATRAN/NASTRAN or MSC NASTRAN) for your analysis. Use bar-elements (preferable) if you design it directly onto the software. You may also use solid elements if you use SW and transfer it into the NASTRAN program. Using bar elements, 1. Discretize the beam into 5, 10 and 20 elements. Does it converge?
